Why does my DADA2 .biom output say OTU ID instead of ASV?

I used DADA2 to process my sequences, which I thought only produced ASVs. However, my .biom table says ‘OTU ID’ as the header. Is the table mislabeled, or did I produce OTUs instead of ASVs?

Hi @KatelynWeeks,

Welcome to the :qiime2: forum!

The biom format is older than ASVs and the standard text header is "OTU ID", regardless of the information that's stored. (And that information could be OTUs, ASVs, molecules, species, high school reading lists...). So, if you didn't do anything else, you have ASVs.



I was looking for this… Finally found this
